I know this isn't typically recommended but I thought I'd share something I actually found quite therapeutic.
After I'd calmed down and composed myself somewhat. Having public ally named, shamed and called them all the names under the sun, I emailed the two other women I had contact details for.
I told them the impact they'd had on both me and the children and they both unreservedly apologised.
Given my behaviour they certainly didnt have to, I honestly feel this did me more good than "dignified" silence whichay have given the impression I didn't care or let them continue with their lives thinking they'd got away with it and maybe doing it again to some other poor married woman.
Anyway just my thoughts on the subject.
